I tried to install auto-cpufreq in both ways, using auto-cpufreq-installer and snap. Neither of ways work out for me.

First I try using snap package, and it gives me this error :

Error output:

sudo snap run auto-cpufreq --monitor

Note: You can quit monitor mode by pressing "ctrl+c"

----------------------------------- Warning -----------------------------------

Unable to detect state of GNOME Power Profiles daemon service!
This daemon might interfere with auto-cpufreq and should be disabled.

Steps to perform this action using auto-cpufreq: power_helper script:
git clone https://github.com/AdnanHodzic/auto-cpufreq.git
cd auto-cpufreq/auto_cpufreq
python3 power_helper.py --gnome_power_disable

Unable to detect if you are using a TLP service!
This daemon might interfere with auto-cpufreq which can lead to unexpected results.
We strongly encourage you not to use TLP unless you really know what you are doing.

So I use sudo snap run auto-cpufreq --debug :

I don't know what I did wrong, I just follow the steps which is mentioned in README.md. It's used to work on my main machine, which I used theauto-cpufreq-installer past 2 months ago. Today I try to install it on my 2nd machine and I didn't work. So I thought of give it try again on the VM. It also give me the same error.

Is there any way to solve this bcoz I really love this.

Running auto-cpufreq on a VM doesn't make sense and will not work, instead run auto-cpufreq on host where VM's are running.
